16 6-10 July 2004 Architecture

17 15-17 November 2004 Free Standard Group: OpenPrinting What is OpenPrinting Architecture ?

OpenPrinting Architecture is a: Reference Model of the overall solution High-Level Architecture abstracting interfaces between components Detailed Architecture defining interfaces between components Architecture elements contain: Reference Model (RM) Overall system diagram Functional decomposition into and description of subsystems. Identification of data and/or control and/or interface between subsystems and/or external systems. High-Level Architecture (HLA) A glossary of terminology. Analysis and documented Use-Cases and requirements. Identification of applicable/recommended standards for subsystem interfaces. Identification of recommended infrastructure for integrating products. Detailed Architecture (DA) Specification of system structure (classes, packages, associations – using UML). Specification of system behavior (activity and sequence diagrams – using UML). Identification of the system process structure. Identification of inter-process communication mechanisms.

An OpenPrinting Architecture: Guides development of abstract interfaces.

18 6-10 July 2004 Free Standard Group: OpenPrinting OpenPrinting Architecture Objectives

Develop a modern Print System for Linux Document realistic Use-Models Extract and analyze requirements Identify applicable, existing, interface specifications for the requirements Apply to multiple print services or be print service neutral. Complete and document Reference Model, High-Level Architecture, and Detailed Architecture.

1.0 Mobile Printing Mobile printing by reference with document data transformation. Example Use Model: Alice goes shopping for a new digital camera to the Fine Camera store downtown. She takes along a magazine review of the new Bright 3000. The sales clerk at the Fine Camera store tells Alice that she would probably prefer the Orion 777. Alice uses her mobile hand-held to browse the Web site of Bright and find the URL for the detailed specs of the Bright 3000. She uses the public access printer in the Fine Camera store to print the Bright 3000 specs. Sure enough, the Orion 777 is a better choice.

40 6-10 July 2004 Application Interface

41 15-17 November 2004 Free Standard Group: OpenPrinting PAPI & Objectives

PAPI stands for: Printing Application Programming Interface Pronounced “pappy” or “P.A.P.I.”

PAPI contains: Data Structures for interacting with basic print service objects. Functions to perform various operations against a print service or it's objects.

PAPI is an API for applications to use to perform print service interaction.

Objectives Provide applications a means of interacting with print services without being tied to a particular service or protocol Allow a rich, extensible set of information to flow between application and print service Support a rich enough set of operations to be useful to most applications with printing needs

42 6-10 July 2004 Free Standard Group: OpenPrinting PAPI Overview

Provides abstraction of server, queues (printers and classes), and jobs.

High-level API focuses on providing a common interface to multiple printing systems and protocols.

Uses extensible attribute sets based on IPP for representing queue and job information. Multi-valued and typed

Currently supports Server connection (and authentication were applicable) Basic queue operations: enumerate, query,enable, disable, modify, enumerate/purge jobs Basic job operations: submit, stream, query, cancel, hold, release, modify

43 6-10 July 2004 Free Standard Group: OpenPrinting PAPI Details

Data types introduced by the PAPI: Service API papi_status_t status/error code enumeration papiServiceCreate papi_service_t server/service connection create a new service object for submitting jobs, listing papi_printer_t printer object/handle/context printers, etc papi_job_t job object/handle/context papiServiceDestroy papi_attribute_t object attributes destroys a service object and all associated resources papi_stream_t stream object/handle/context papiGet*() / papiSet*() papi_job_ticket_t job ticket Get or set the corresponding service object attributes papi_filter_t filter for limiting printer lists (UserName, Password, Encryption, AuthCB, AppData)

73 6-10 July 2004 Free Standard Group: OpenPrinting Backgrounds (Cont.)

Needs to control the multi-channel data flow. Who controls? Each printer/protocol has its own commands and procedures. Who deals with the printer/protocol dependencies?

PCM Should be separated into two layers; Core module providing the multi-channel functionalities. Plug-in providing each printer/protocol dependent functionalities.

76 6-10 July 2004 Requirements for Plug-in

77 15-17 November 2004 Free Standard Group: OpenPrinting Basic Requirements

Plug-in must; A-1) Provide the API for; Writing a printing data to the printer. Reading a printer status data from the printer.

A-2) Conceal the printer/protocol dependencies. PCM can deal with all the printers/protocols (e.g. IPP, etc..) as an unified object via each Plug-in.

A-3) Provide the API that can be applied on both; Big memory system. Small memory system.

78 6-10 July 2004 Free Standard Group: OpenPrinting Port Control Requirements

Plug-in must; B-1) Conceal the port control procedures based on each printer/network protocol dependencies. Open / Close a USB port, etc... Open / Close an IPP port etc... Port must; B-2) Be specified by the generic device/network protocol identifier. URI ?

79 6-10 July 2004 Free Standard Group: OpenPrinting Data Reading Requirements Plug-in must; C-1) Provide a generic API for sending back the variable length printer status. Printer status data length depends on each printer model and conditions of the printer. Plug-in may separate a single very long printer status data into a set of several short data for sending them back into a short restricted buffer prepared by the upper layer.

C-2) Provide the API to know the top of the printer status data and/or to reset the reading position of it. The upper layer doesn’t know what the status data includes(binary, XML, etc…), but needs to know the top of it. Reading a printer status data may be interrupted by a signal.

80 6-10 July 2004 Free Standard Group: OpenPrinting Data Reading Requirements (Cont.)

Plug-in must; C-3) Keep the printer status data consistent until all the status data are read by the upper layer. Plug-in needs a trigger to allow for reading a printer status from the printer/network port. C-4) Provide the API which gives a trigger to the Plug-in for dealing with reading a printer status data and writing a printing data exclusively. Some printers/protocols have to deal with reading a printer status data and writing a printing data exclusively, and the Plug-in needs a trigger for doing it.

81 6-10 July 2004 Free Standard Group: OpenPrinting Data Writing Requirements

Plug-in must; D-1) Provide the API which gives a trigger to the Plug-in for dealing with reading the printer status data and writing the printing data exclusively. Same as C-4) of the Data Reading Requirements. Writing a printing data may be interrupted by a signal.

82 6-10 July 2004 Free Standard Group: OpenPrinting Dataflow Control Requirements

Plug-in must; E-1) Let the upper layer know; If the Plug-in is ready to receive a printing data. If the Plug-in is ready to send back a printer status data.

Plug-in should; E-2) Provide the API being not affected by OS platform dependencies.

83 6-10 July 2004 Free Standard Group: OpenPrinting Printer Control Requirements Plug-in must; F-1) Provide the API to cancel a printing. The upper layer keeps alive the Plug-in for obtaining the printer status continuously across several printing jobs. Each printing job’s printing data might be specified by an identifier for the cancellation. (TBD) Example) In case of the upper layer sends two job’s printing data to the Plug-in. After the upper layer finished to send the first job’s printing data to the Plug-in, the upper layer can start to send the second job’s printing data while the Plug-in may send the first job’s printing data to the port. During this period, the first job has not been finished, and if the user wants to cancel the second job after noticed the mistake, the upper layer needs an identifier to cancel the second job’s data buffering, or cancel the first job.

Upper Cancel Plug-in Printer Layer Write Write 2nd Job’s Printing Data 1st Job’s Printing Data

84 6-10 July 2004 Free Standard Group: OpenPrinting Printer Control Requirements (Cont.)

Plug-in might (TBD); F-2) Provide the API for the common control functions. “Pause”, “Resume” for local port printers as well as IPP ? IPP needs a job identifier to control a job.

F-3) Provide the API for tracking printing jobs. Plug-in for IPP will be provided, while IPP provides job attributes. If PCM is the “only” interface to access a printer, PCM might provide the interface for tracking printing jobs in a printer to satisfy some applications needs.

85 6-10 July 2004 Plug-in API Design

86 15-17 November 2004 Free Standard Group: OpenPrinting Object / Port Control

Object Control New z Conceal the printer/protocol dependencies in the created object. z Object keeps the URI specified by the upper layer until destroyed.

Destroy z Destroy the object.

Port Control Open z Open the printer / network port specified by the object.

Close z Close the port / network port specified by the object.

87 6-10 July 2004 Free Standard Group: OpenPrinting Data Reading

StartRead z Declare the start of reading a printer status. z Reset the reading position of the printer status data in the object.

Read z Read the specified byte length of a printer status data from the object, and store them in the buffer given by the upper layer. z Returns the status data byte length read from the object, or zero when no status data remains in the object.

* The data format of the printer status is out of scope of this API.

EndRead z Declare the end of reading a printer status.

88 6-10 July 2004 Free Standard Group: OpenPrinting Data Writing

StartWrite z Declare the start of writing a printing data.

Write z Write the specified byte length of a printing data in the buffer given by the upper layer to the object. z Returns the printing data byte length written to the object, or zero when no printing data written to the object.

EndWrite z Declare the end of writing a printing data.

89 6-10 July 2004 Free Standard Group: OpenPrinting Dataflow Control

GetReadFD z Obtain the reading file descriptor for select() use. z The upper layer know by select() if the Plug-in is ready to send back a printer status data.

GetWriteFD z Obtain the writing file descriptor for select() use. z The upper layer know by select() if the Plug-in is ready to receive a printing data.

Reading / Writing Control Process The upper layer deals with control all the reading/writing request by select(). Plug-in for each Printer / Protocol

90 6-10 July 2004 Free Standard Group: OpenPrinting Printer Control

StartJobData z Declare the beginning of the printing data of each job to the object.

CancelJobData z Cancel the printing data specified by the job identifier.

EndJobData z Declare the end of the printing data to the object.

ExtCtrl z Execute the extended printer control, such as “Pause”, “Resume”...

91 6-10 July 2004 Status Monitoring

92 15-17 November 2004 Free Standard Group: OpenPrinting Just an Idea

Requirements Status Monitoring Interface must; Translate the printer status data read from each Plug- in into the generic format data that does not depend on each printer/protocol.

Generic format is XML? IPP? other?

93 6-10 July 2004 Free Standard Group: OpenPrinting Just an Idea (Cont.)

API Design New z Conceal the printer/protocol dependencies in the created object. z Object keeps the “language” and “character encoding” specified by the caller (module which calls this API) until destroyed. StartTranslate, Translate, EndTranslate z Translate the printer status data given by the caller to the generic format data, and store it into the buffer given by the caller. Destroy z Destroy the object.

94 6-10 July 2004 Issues/Concerns, Next and Info.

95 15-17 November 2004 Free Standard Group: OpenPrinting Issues/Concerns, Next
